ICC_Profile Tags

ICC profile information is used in many different file types including JPEG, TIFF, PDF, PostScript, Photoshop, PNG, MIFF, PICT, QuickTime, XCF and some RAW formats. While the tags listed below are not individually writable, the entire profile itself can be accessed via the extra 'ICC_Profile' tag, but this tag is neither extracted nor written unless specified explicitly. See http://www.color.org/icc_specs2.xalter for the official ICC specification.
